Hi

Just a I'm very new to the forum.
I just tried for the first time the mock exam at: http://www.javaranch.com/carl/scwcd/scwcd_mock.jsp
and after (the last?) question I got:


Error page Scwcd_Error

An error occured in the bean. Error Message is: null
Stack Trace is :

java.lang.NullPointerException
at com.javaranch.jspbeans.scwcd.QuizBean.execute(QuizBean.java:216)
at __jspPage730_carl_scwcd_scwcd_mock_jsp._jspService(__jspPage730_carl_scwcd_scwcd_mock_jsp.java:89)

at com.evermind._co._fs(.:189)
at com.evermind._bt.run(.:62)

Did anybody get this problem before ? I left a couple of question un-answered, could it this be the origin of the exception?

PS: Not sure this is relevant to this forum: please be free to move this into a more appropriated forum.
